CATCH-BASIN COVER AND SEWER-INLET.

SPECIFICATION forming part of Letters Patent No. 714,185, dated November 25, 1902.-

Application filed June 21,1901- To all whom it nuty concern:

Be it known that we, FREDERICK H. JACK- SON and GEORGE M. PIERCE, citizens of the United States, residing at Cleveland, in the county of Ouyahoga and State of Ohio, have invented certain new and useful Improvements in Catch-Basin Covers and Sewer-Inlets; and we do declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

Our invention relates to catch-basin covers and sewer-inlets; and the invention consists in a cover or inlet of this kind and a dripplate adj ustably fixed at its ends to or on the wall of the said cover or inlet, whereby the said plate can be set at any desired elevation according to the level of the street-paving and is permanently held at such level through its connections with the supports at its ends, all substantially as shown and described, and particularly pointed out in the claims.

In the accompanying drawings, Figure 1 is a perspective view of a catch-basin cover with our improved construction of drip-plate therein, and Fig. 2 is a cross-section of said cover and plate front to rear. Fig. 3 is a perspective view of the drip-plate alone. Fig. 4 is a perspective view of the sewer-inlet or curbbox and inlet with our plate fixed therein. Figs. 5 and 6 are perspective views of modifications of the drip-plate, as hereinafter fully described.

We are of course aware that drip-plates as such are not new in this art and that such plates have heretofore been variously used I and adapted to be raised and lowered in respect to the casing, cover, or inlet to meet the street elevation and paving, and some such adaptations and uses have required a base of masonry to support the said plate. By our improvement the ends of the said plate are adapted to be adj ustably attached to the adjacent wall of the casing, cover, or box and no other supporting medium is used or required. In this we regard our invention as broadly new.

Now referring to Figs. 1, 2, and 3, A represents what at this time is a popular form of catch-basin cover or casing, the same having its front closed across its top and open at its but this need not necessarily be.

bottom and having parallel side walls in which are formed a set of vertical slots at at each side. A single slot would suffice in some places and with certain constructions, but with the present style of cover two slots are altogether preferable.

B is one form of our new drip-plate, the construction of which is clearly shown in Fig. 3. In this form the said plate has a front down-flange 2, adapted to abut against the inner wall of the street-paving, Fig. 2, an inwardly and downwardly inclined top portion 3, which may be curved in cross-section instead of straight and is always designed to be flush with the surface of said paving at its outer edge. Then there are end flanges or ears 4, with perforations through which the said plate is bolted or fastened through slots a into working position.

Obviously the flanges 4 might be slotted instead of perforated, so that both parts would have slots, and the said cover or casin g might have perforations in lieu of slots, so that in this respect the present construction would simply be reversed.

In Fig. 4 the'inlet-box or casing C has a single slot 0 in lieu of two, as in Figs. 1 and 2; but otherwise the relation of the said part with plate D is the same as in the other views with plate B. This casing or inlet-box has a bottom 5 formed in a separate piece with an opening 6 for a sewer-pipe connection; The front flange dis deeper in this instance than flange 2 on plate B, so as to overlap the edge of the lower plate 5, even at its highest adjustment.

In Fig. 5 we show a section of a drip-plate G having flange g, top portion g, end flanges g and rib g above flange g. This is designed to be set so as to prevent sand overflowing into the basin. We could do this also by adjusting either plate B or D high enough to form a barrier to sand in like manner.

In Fig. 6 we show a section of a drip-plate H, which has flange h in front, top h, end flanges W, and upward projections h at intervals above flanges h, serving to catch debris that might otherwise flow into the basin and become an obstruction. In both cases the upward projection stands above the level of the adjacent paving.

Obviously the overflow plate is equally adaptable to still other styles pf catch-basin covers, casings, or inlets, so that the invention is not limited to any particular style of these parts, and the term easing as herein used covers the style of cover shown in Fig. l and inlet-box in Fig. 4, and other covers, boxes, and casings serving a like purpose and adapted to utilize our adjustable overflow-plate.

What we claim is- 1. In catch-basins and like sewer-inlets for streets, a suitable casing and a drip-plate adjustably supported at its ends on said casing, substantially as described.

2. A casing substantially as described, and a drip-plate, said parts constructed to adapt the elevation of the plate to the elevation of the street-paving, and means comprising bolts and nuts to secure the said plate adjustably to the casin g, substantially as described.

3. The casing open at its bottom and having vertical slots at its sides, in combination with the drip-plate constructed to fit Within said casing and having openings at its ends, and bolts through said openings and the slots in the casing to fasten the plate, substantially as described.

4. A drip-plate for catch-basins and the like having its ends constructed to be adjustably secured in Working position and provided with a down-flange along its front edge, substantially as described.

5. In a catch-basin, the combination of a suitable supporting part adapted to be disposed at the mouth or entrance of the catchbasin, and a sill for said mouth or entrance adj ustably secured to said part, substantially as described.

Witness our hands to the foregoing speci- 4o
